Specification of Letters Patent.

Patented Nov. 1, 1910.-

Application filed September 17, 1909. Serial No. 518,166.

To all whom it may concern:

Be it known that I, CARLTON A. MUNGER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Gearing, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention consists of mechanism for operating washing machines, and particularly for the type of machine constituting the subject-matter of my copending application, Serial No. 497,595, filed May 22, 1909.

In the drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation; Fig. 2 is a front elevation; Fig. 3 is a detailed view, on an enlarged scale and in plan view, of the mechanism for producing rotary reciprocatory movement of the cyhnder or like parts; Fig. 4 is a side elevation of the same; Fig. 5 is a sectional view on the line 5--5, Fig. 3; Fig. 6 is a detail of the means for transforming rotary reciprocatory movement of the clothes cylinder orlike part into continuous rotary movement, as, for instance, in the operation of the wringer rolls; Fig. 7 is an end elevation of Fig. 4; and Fig. 8 is a side elevation of means for shifting the power drive from its connection with the clothes cylinder to actuating connection with the wringer.

The .casin .1 is intended to contain the water, and 1s preferably provided with a rounded bottom 2. Said casing is preferably supported by legs 3, which can be connected by a cross-piece 4 or a plurality of such pieces. When an electric, motor 5 or a water motor or the like is used, it may be conveniently attached to one of said crosspieces and the operating fluid may be led to and from same by the conductor 6, which, in the case of electric wires will be overned by the button 7. The clothes cylinder or barrel 8 is provided with a stud 9, which projects from one end thereof and 1s adapted to rotate in bearing 10. At the other end of the barrel a casting 11 is attached thereto, into an open space in which projects the square hub 12 of gear 13, which is mounted on short shaft 14, projectin from casting 15 attached to one of the si es of easing 1.

Forked casting 11 is adapted to receive and hold the square hub 12 of gear 13, whereby the barrel to which said casting is attached is caused to rotate with gear v13 on shaft 14..

It should be noted that, while'the squared or other rectangular form for the hub- 12 and for the bearing within casting 11 is preferred, nevertheless other angular forms can be substituted therefor, or other forms 10f engagement between the barrel 8' and the ear 13 may be utilized.

T e mechanlsm may receive its power from any suitable source, but in the drawings is shown as actuated by a belt 16 driven by the motor 5, said belt 16 leading to a wheel 17 mounted on shaft 18. i

A air of grooved pulleys 19' and 20 bearing emale friction cones 21 a'nd 22, which cones face toward each other, are mounted on shaft 23. A pair of belts 24 and 25 drives said pulleys 19 and 20 -from pulleys 26 and 27 mounted on shaft, 18 in such manner as to rotate with wheel' li, one of said belts being crossed so that the pulleys 19 and 20 will rotate in op osite directions, notwithstanding the fact tiat wheel 17 and pulleys 20, 26, and 27 all rotate in one direction. Shaft 23 is supported by a casting 28 and the supports for other moving parts, to be more particularly hereinafter described, are, also, borne by'the same casting, thus insurin that, in case of warpin of the wood-work y reason of moisture, t e relation of the principal moving arts will at all times remain the same. T e outer end of said shaft 23 is journaled in arm 29, which is attached by bolts 30 to said ca st ing 28. A casting 31, having a groove 32 therein, receives a slidable block 33, which slide thereon and alternately to engage 'female friction cones 21 and 22. Dependent on whether said male cone is cooperatin with female cone 21 or female cone 22, she. t 23 is rotated either forwardly or rearwardly, as pulleys 19 and 20 rotate in o posite directions. A pinion 36, mounte on the inner end of shaft 23, is driven thereby and is in constant mesh with shiftable pinion 37, andwhen the latter is in en agement with gear 13, rotates same and, t ere- The result of the alternate engagement of the double male friction cone 35 with the female cones 21 and 22 is that reci rocatory rotary motionis imparted to sha t and, thus, to pinions 36 and 37, and in that manner to gear 13 and the'cylinder or barrel 8 driven thereby.

Afterv the clothes have been adequately washed by the tumbling of them in the soapy water caused by therotation of the 15 barrel. in which they are contained, the surging of the water in and. out of said barrel and through the clothes, due to the movement of the barrel, also assisting in the cleansing process, it is desirable toWring same from said barrel into a receptacle containing rinsing water by a direct operation without the necessity of first carrying the washed articles from the washer to some other place. In order to make this operation possible and thus obtain the convenience arising therefrom, a clothes wringer 38 is secured to the casing 1. To save manual operation of said wringer, and in order to operate it by the same power and 3 mechanism which has been utilized in producing the movement of the clothes cylinder, the shiftable pinion 37 is lifted from engagement with gear 13 into mesh with gear 39 mounted on the extension 40 of the shaft 35 of one of the wringer rollers. The pinion 37 is mounted on the end of an arm 41 pivoted on shaft 23. Another arm 42 is rigidly secured to shaft 43, which is rotatable by lever 44 havingthe handle 45, which lever '40 44 is also rigidly secured to said shaft 43.

When pinion 36 is causing cylinder 8 to rotate, the several parts are in the position 'shown in full lines in Fig. 8. When work of the washer has been accomplished, and

it is desired to wring the clothes from the washer into the next receptacle, usually containing rinsing water, the handle 45 will be pulled from the full line position in Fig. 8 to the position depicted in dotted lines,

which movement causes arm 42 to rise to the clotted-line position, pulling link 46 with it and, thereby, raising pivoted arm- 41 to the dotted-line position and with it pinion 37 so as to engage gear 39, as shown by the 5 dotted-line illustration ofpinion 37.

It is a greatadvantage in the economy of a laundry to be able to save labor byutilizing mechanical power in wringin the clothes out of the washer into the rinsing 0 water, and it is a particular advantage of this machine that it provides means for utilizing thesame power both for washing and wringing. This desideratum is produced in this machine by the means pro- 65 vided by throwing the driving mechanism pintle 71.

into engagement at will with either the washer or the wringer. In order to hold the shiftable pinion 37 into firm en agement with gear 39 or car 13, it is desira lethat a lock be provided to prevent movement thereof when it has been shifted to the desired position. A spring-pressed bolt 47, controlled by the pivoted handle 48, is adapted to seat in notches 49, 50, and 51 in the periphery of plate 52, said bolt movin through perforations in lugs 53 connected with lever 44. When bolt 47 is seated in notch 49, pinion 37 is held in engagement with gear 13. When said bolt is seated in notch 51, pinion 37 is held in engagement with gear 39, sothat the lower roll of the wringer is driven thereby.

The male cone 35 is actuated alternately to enter and engage the female cones 21 and 22' by the cam disk 54, in the periphery of which are cut notches 55 and 56, saidcam disk being caused to rotate by means of pawl 57, which engages ratchet 58, which is mounted on shaft 59 and-to which cam disk 54 is rigidly secured. Said pawl 57 is mounted on a link 60 pivoted to shaft 59 and also pivoted to arm 61 eccentrically connected at 62 to gear 63 driven by pinion 64'formed on or driven by pulley 20. While cam disk 54 is rotating, roller 65 is riding on the side thereof adjacent its peri hery and in circumferential alinement Wit notches 55 and 56 andcam faces 66 and 67. Said roller 65 is support- I ed from plate 68 pivoted at 69 to arm 70 by As roller 65 rides alternately first on one side and then the other of cam disk 54, it causes double male cone 35 to engage either female cone 21 or female cone 22 by reason of its connection through plate 68 with arm 70, which is pivotally attached at 72 to said male cone 35 and ivoted at 73 to bracket 74 attached to casting 28. The swinging of arm .70 on pivot 73 causes double cone 35 to slide to the right or the left on shaft 23 and thus engage alternately the female cones, which rotate in opposite directions by reason of the direction of .movement of pulleys 19, and 20. The rotation of the double cone 35 by the particular female cone with which it at any time isengageddrives shaft 23 in the same direction by reason of the spline 75, or similar connection between sald cone and said shaft.

Vhen the rotation of the cam disk 54 has brought notch 55 adjacent rollerv 65 to engage cam face 66 and to ride through notch 55 into the position depicted in Fig. 7, further travel of said roller 65'will then be upon the right-hand side of cam disk 54 until notch 56 is reached, whereupon cam face 67 is engaged by roller 65, with the result that roller 65 is carried through to the left-hand side of said disk until it again reaches notch 55 and again engages cam face 66. The transfer of roller 65 from one side comes to the 'other of the disk 54 rocks arm on pivot 73 and slides double cone 35 on spline 5, as hereinbefore mentioned.

In order to provide an ad'ustable connection between roller 65 an arm 70, said roller is attached to plate 68, which plate is ada 'ted to rock on 1ts pivotal connection 69 wit rod 70; but the degree of movement of plate-68 is limited by the adjustment provided' by set-screws 76 and 77, which pass throu h lu 78 and 79 ro'ectin u wardl from %)late%i 8. When, tliiodgh w ar br othe r circumstances, it is found that, by the trans fer of the roller 65,from one side to the other of disk 54., cone 35 is not caused to engage the coiiperating female cones tightly enough, the degree of friction can be increased by screwing the set-screws 76 and 77 farther in toward the end of arm 70, thus reducing the play of plate 68. On the other hand, if it is found that the friction between cone 35 and the e05 crating female cones is too eat or too su den, more play can be pro need by retractin the set screws from arm 70 and allowing greater play of late 68.

One 0 the advantages of this mechanism is that due to the slipping between the male and female friction cones, the cylinder 8 does not, at the end of its travel 1n one direction, sto rotation suddenly or with a jar or poun but in a slightly gradual manner, preparatory to beginning to revolve in the opposite direction. In t is respect, and for this reason, the application of a friction drive to the reciprocatory rotary movement customary in a washing machine is of great advantage, as the reversal of the direction of movement of the cylinder merely by gears would be accompanied by the objectionable jarring due to too sud on change of direction.

Ordinarily, reci rocatory rotaig move ment of the cylinder 8 will be esirable, while, on the other hand, continuous rotation in the same direction of the driving roll of the wringer will be preferable. In order to produce these opposite kinds of motion in this machine and at the same time retain the advantage of interchangeably using the samedrivmg mechanism for the wrin er and the washer, means must be provide for transforming the reciprocatory rotary movement of shaft 23 when engaged in driving the washer cylinder into continuous rotary movement when the same shaft is drivin the wringer. is found in t e detent 80, which, while normally occupying the position shown in full lines in Fig. 6 allowln pawl 57 to engage ratchet 58, whereby t e reciprocatory rotary movement of shaft 23 is produced, as hereinbefore' described, can be moved to the position shown in dotted lines in Fig. 6, thus lifting said pawl from engagement Such means a with said ratchet by engagement of detent 80 with pin 81, projecting from pawl 57. When pawl 57 18 thus disengaged from ratchet 58, cam disk 54 ceases to rotate, and one end of double male friction cone 35 is allowed to remain continuously in engagement with its coiiperating female friction cone, and thus continuous rotary motion is imparted to shaft 23. Dependent upon which female friction cone -1s engaged by the male friction cone at the moment when the detent 80 lifts pawl 57 from ratchet 58, said continuous rotary motion of shaft 23 may be in either direction with the result that the wringer may be used to wring= clothes. either taken om cylinder 8 and passed through the wringer into rinsing water or that are taken out of some other receptacle and passed through the wringer into cylinder 8. If said detent be not raised, the wringer would operate with a reciprocatory rotary motion. If continuous rotary movement in either direction of cylinder 8 be desired, detent 80 may be raised and said 8 mi ht be made such that the clothes would be a equately agitated therein by continuous rotation thereo .Moreover, the interior construction of barrel The 0 eration of the mechanism is as follows: I electricity be the motive fluid, the button 7 will be turned so as to close the circuit. Belt 16 will drive wheel 17- and with it pulleys 26 and 27 and, in opposite directions, pulle s 19 and 20. Pinion 64 drives gear 63 an thus actuates arm 61. The eccentric thrust and retraction of arm 61 causes awl 57 successively to engage the teeth of ratchet 58 and thus to rotate cam disk 54. The rotation of said disk presents cam faces 66 and 67 alternately and successively to engagement with roller 65, which rides thereon, and is thereby caused to pass from one side to the other of disk 54, said cam faces 66 and 67 leading the said roller in opposite directions. Passage of roller 65 from one side to the other vof disk 54 rocks arm 70 and pushes either. one end or the other of double male cone 35 into engagement with either one or the other of the female cones 21 and 22. The direction of oslate alternately to the right and to the left,

and 'thus to cause cone 35 alternately to engage female cones 22 and 21. Gone 35 being splined to shaft 23, when cone 35 is in engagement with. either cone 21 or cone 22, shaft 23 is driven in the same direction as the direction of the rotation of the female cone 21 or 22 thus engaged, the direction.

of said female cone being that of the pulley 19 or 20 with which it is connected, said pulleys rotating in opposite directions. Thus, when cone 35 is in engagement with cone 21 driven by pulley 19, shaft 23 is rotating in one direction, and when cone 35 is in engagement with cone 22 driven by pu1- ley 2O shaft 23 is rotating in the direction opposite to that inwhich it rotates -whencone 35 engages cone 21. Dependent upon whether interchangeable pinion 37 is in engagement with gear 13 or wringer gear 39, either the barrel 8 is reciprocatingly ro-- tated or the wringer roll is driven. In the latter case, detent 80 will have been raised while shaft 23 is rotating in the direction that will produce the desired direction of wringing through the wringer, and, by reason of detent 80 having lifted pawl 57 out of engagement with ratchet 58, the direction of wringing will be continuously in one direction (unless, in exceptional cases, reciprocatory' rotation of the wringer rollers is unobjectionable or desirable), while, on the' other hand, when pinion 37 drives barrel 8 from shaft 23 pawl 57 will generally be in engagement with ratchet 58 to produce reciprocatory rotation of barrel 8, except in unusual instances or uses where constant rotation of said barrel in one direction is desirable.

It will be observed that, as the roller 65 is always on either one side or the other of cam disk 54, except at the particular mo-- ment when sameis riding on the middle of either cam face 66 or cam face 67, male cone never occupies a neutral position, but is always in; engagement with either friction cone 21 or friction cone 22.

It will be obvious that many minor changes in the form, arrangement, location, and relation to each other of the several parts may be made without departing from thespirit of the invention, which is more particularly pointed out by the following claims.
